SGR,
Typically I face up-wind and if with a partner which is pretty much all the time, one of us will face down wind also, best of both worlds. Typically I place myself in stands that prohibit a rear entry without having to come around in front of me, whether it is up wind or down wind that I am facing, i.e. Cliffs, Large Hills, or just flat NON coyote country.
The more I learn about coyotes and the more videos I watch, it seems nobody agrees with the proper direction. I grew up in wyoming where wind is almost constant and I have always faced into the wind unless I have no other choice but to face down wind. With coyotes, they will come in any direction they please. Typically the ones I call in come from upwind and try to work down wind, now if I didnt see them, they would come from downwind, I just haven't shot any from down wind and I believe it is because of the areas I hunt, open and visible.
I know, no hard recommendation, but just wait to see your responces here. I think the best idea is, base it on stand by stand situations.
If you hunt with a rifle, facing down wind is feasible, with a shotgun I am not so sure, they have incredible noses and getting them in range may be harder. In brush country I think facing down wind is a good choice, they do love to circle down wind and in brush country I am guessing they are more like to have come from any direction but end up down wind right in front of your face, or behind your back which ever the case may be.
Goodluck with this one,
